Answer:
29,800
Step-by-step explanation:
that will be 149 x 2 which equals 298
149
×2 Multiply 9 × 2 = 18
------ Keep the 8 carry the 1 multiply 4 by 2 then add 1 finally multiply 2 by 1
298
Then add two zeros at the end since we're multiplying a number with two zeros. (This method only works for numbers that end with zeros)
Final answer: 29800
Pick 2 points off ur line...it is easier if u pick whole number points
(2,0) and (0,5)
slope formula = (y2 - y1) / (x2 - x1)
now label ur points
(2,0)...x1 = 2 and y1 = 0
(0,5)...x2 = 0 and y2 = 5
now sub and find the slope
slope(m) = (5 - 0) / (0 - 2) = -5/2 <====
150 x 12 = 1800
55 x 12 = 660
1800 + 660 + 45000 = 47,460
Answer:
The mean of X is 122.5 and the standard deviation is 7.9.
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they believe that the overall state of moral values is poor, or they do not believe this. The probability of an adult believing this is independent of other adults. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
In this problem, we have that:
So
The mean of X is 122.5 and the standard deviation is 7.9.
Okay so I'm going to set up a equation:
5.27= 3.40+ 0.85x, we have our total our price of one pineapple and our variable
next I isolate the variable:
5.27-3.40=0.85x
next:
1.87=0.85x
x= 2.2
she bought 2.2 pounds of tomatoes
